How to Build industrial platform step ladder？
Use aluminum profiles and accessories
80×80, 40×120 profiles are used for the main support frame of the lower floor, connected by 4080 and 8080 die-casting angle aluminum
The steps of the steps and the upper platform use step profiles (it can be used as a platform instead of a board after splicing, which is more beautiful and faster)
The upper yellow plastic-sprayed part is the guardrail, which is connected by 40×3 aluminum round pipes and matching joints
